Quicklook From the Command Line

This Mac
OS X hint shows how to use Quicklook from inside Quicksilver.
I'm a big Quicksilver fan, but frankly didn't get very excited since
just hitting "return" launches Preview as fast as hitting "tab->q"
and then waiting for the AppleScript to run. But, along the way,
part of the hint involved creating a small shell script:

#!/bin/bash
qlmanage -p "$@" >& /dev/null &

Using the script, you can launch QuickLook from the command line.
Now that's handy!

qlmanage is a very chatty program that performs operations
on the QuickLook cache and generators. I saved the above script as
ql.
